Replication redefined: How we built a low-latency, multi-tenant data replication platform | Datadog

What this post added

This post details the creation of a managed, multi-tenant data replication platform at Datadog. It describes the initial problem of scaling a shared Postgres database for search queries, leading to the architectural decision to replicate data to a dedicated search platform, reducing page load times by 97%. It then covers the automation of replication pipeline provisioning using Temporal workflows, breaking down complex steps into modular tasks. Finally, it discusses the choice of asynchronous replication for low-latency, high-reliability data movement, contrasting it with synchronous replication and highlighting its benefits for multi-tenant systems.
